Van Halen - Grammys or no Grammys ????

Assuming that a post on the official twitter account for the Grammys suggested that Van Halen would appear onstage 11/30/11 at the Grammy nominations show to announce their reunion plans??? A source tells Rolling Stone magazine that a VH Grammy show appearance is not in the cards, although a spokesperson for the Grammys did not immediately respond to a comment request ?????
WTF???
